P0695
Fan 3 Control Circuit Low
The control line for cooling fan 3 (typically condenser fan or auxiliary fan) is shorted to ground. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
